      Product details

      Amino Trimethylene Phosphonic Acid ATMP

      CAS No: 6419-19-8

      Molecular Formula: C3H12NO9P3

      Formula Weight: 299.05 g/mol


      Industry Uses

      ● Water treatment products

      ? ATMP is a kind of scale and corrosion inhibitor with low toxicity, good thermal stability, resistant to hydrolysis, and chemical stability. It can form multicomponent complex with calcium, magnesium and other metal ions. It has good properties of chelation, low threshold inhibition, and lattice distortion. It also has good synergistic effect with polyphosphate, polycarboxylate and nitrite.

      ? As a scale and corrosion inhibitor, ATMP is widely used in industrial circulating cooling water, oilfield water injection and printing and dyeing water systems. ATMP can also be used as metal cleaner to remove grease from metal surface, detergent additive, metal ion masking agent, cyanide free electroplating additive, precious metal extractant, etc.

      ? ATMP is often used with other organic acid, polylactic acid or salt to form organic water treatment agents for circulating cooling water systems under a variety of different water quality conditions.
